Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Control DC Motor with Raspberry Pi 3. We will control both the speed and direction of DC Motor. I hope you have read the previous tutorial on How to Create a GUI in Raspberry Pi 3 as we are gonna create a small GUI in this tutorial as well and then we are gonna control our DC Motor with Buttons on GUI.
In order to control the DC Motor, we have to use some drivers in between our Microcontroller and DC Motor. This driver's functionality is to control a 12V DC Motor with a 5V signal from a microcontroller. In today's tutorial, we are gonna use L298 Motor Driver. So, let's get started with How to Control DC Motor with Raspberry Pi 3:
How to Control DC Mot ...
Hello readers, I hope you all are enjoying our Raspberry Pi Pico programming series. In our previous tutorials, we learned how to access Raspberry Pi Pico’s GPIO pins for both input as well as output operations. For demonstration, we used LED as an output component and a push button as an input component.
Now let’s learn how to interface sensor modules with the Raspberry Pi Pico module. So, in this tutorial, we will learn how to interface the DHT11 sensor with the Raspberry Pi Pico module and fetch the observed data (from its surrounding) using the MicroPython programming language.
Before writing the code for interfacing and fetching the data from the respective sensor, let’s first have a look at the working operation, features and properties of the DHT sensor.

Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of pulse width modulation (PWM) in Raspberry Pi Pico using the MicroPyton programming example. We also implemented the LED brightness control program to demonstrate an application of the pulse width modulation technique.
In this tutorial, we are going to implement another application of pulse width modulation technique which is ‘Direction and position control of a servo motor’ with Raspberry Pi Pico module and MicroPython programming language.
Later in this tutorial, we will also discuss how to control the position of a servo motor with push buttons (to be used as control inputs) and also to use LEDs for indication purposes.
What is Servo Motor?
Before interfacing the servo motor with ...
Welcome to the next tutorial of our raspberry pi four programming course. Before, we saw how to connect a Raspberry Pi 4 to a relay with four independent channels. To complement the relay circuit, we programmed a python script to turn on and off a single bulb. However, in this tutorial, we'll show you how to connect a GPS module to a Raspberry Pi 4.
Raspberry Pi 4, one of the most popular embedded platforms, has made it simple for developers to obtain location data via a GPS module, allowing them to create devices with a greater reliance on precise positioning. Because of the Raspberry Pi's impressive processing capabilities, this essay focuses on the exciting prospect of creating GPS-based projects using the same inexpensive GPS chips.
Since thi ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to how to tweet from Raspberry pi. We also discussed some methods used by the tweepy library to perform some API calls in our project. We will learn how to print from a Raspberry pi in this lesson.
Let us get started
There are several benefits of having a print server. Print servers may link numerous computers to one or multiple printers, either physically or wirelessly, allowing you to access the printer with various devices and send print instructions from all the other connected computers.
It is not easy to print from an Android smartphone to a cabled printer; however, a printer server makes it simple. A print server is useful in small workpl ...
Hello friends, I hope you all are doing well. Welcome to the next tutorial of our Raspberry Pi 4 programming course. In the previous lecture, we interfaced LCD 16x2 with Raspberry Pi 4. Today, we will interface a keypad 4x4 to Raspberry Pi 4. In embedded projects, a keypad is used to get user input i.e. calculator, ATM keypad etc. Different types of Keypads are available i.e. 4x4, 4x3 etc.
So, let's get started:
Components Required
We will need the following components in our today's project:Raspberry Pi 4Keypad 4x4BreadboardConnecting Wires
Keypad 4x4
A keypad is a collection of push buttons, arranged in a matrix form.Keypad 4x3 means the keypad has 4 rows and 3 columns and 12 buttons in total. A 4 by 4 keypad membrane has 8 pins in t ...
Welcome to the next tutorial in our Raspberry Pi 4 programming tutorial. In the previous tutorial, we learned the basics of using a Raspberry Pi as the basis for an Internet of Things-based weather station. However, this is a continuation of the previous tutorial. In the subsequent session, we will learn how to develop the Python code that will bring our weather station circuit design to life. Before that, let us learn how to measure wind direction and rainfall.
Wind direction
Wind vanes
Despite their name, wind vanes do not indicate a change in wind direction. Since the arrow on most television weather maps goes in the opposite direction, this may come as a surprise at first. To determine the wind's direction, a wind vane uses the force of the wind on a vertical blade, which then spins ...
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we integrated a real-time clock with our raspberry pi four and used it to build a digital clock. However, In this tutorial, we will construct your personal Twitter bot using Tweepy, a Py framework for querying the Twitter application programming interface.
You will construct a Response to mentions robot that will post a response to everybody's tweet mentioning it with a certain keyword.
The response will be a photo we will make and put any text over it. This message is a quote you will acquire from a 3rd application programming interface. Finally, we will look at the benefits and drawbacks of bots.
This is what it looks like:

Introduction
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, a facial recognition system on a Raspberry Pi 4 was used to develop a smart security system. We also learned how to create a dataset using two Python scripts to train and analyze a series of photographs of a certain person. This tutorial will teach you how to install pi-hole on a Raspberry Pi 4 and use it to block advertisements from anywhere. This is a great initiative for folks who are tired of annoying pop-up adverts while browsing. First, we'll learn how to set up the pi-hole without the need for an environment, then we'll use Docker to install pi-hole, and ultimately we'll see how we can access it from anywhere.

Hello friends, I hope you all are doing great. Welcome to the 11th lecture of Section-III in the Raspberry Pi 4 Programming Series. In the previous tutorial, we discussed the interfacing of the Fingerprint sensor with Raspberry Pi 4. Today, we are going to discuss another sensor named the Pulse rate sensor and will interface it with Raspberry Pi 4.The field of healthcare monitoring has long been seen as a potential use
case for IoT i.e. examining the health
instead of regular checkups and local doctors. Using sensors,
your vital signs can be monitored and transmitted in real time, allowing
a physician on the other side or even an AI to analyze the data and
provide an accurate diagnosis. That does seem somewhat futuristic.
However, we are making steady progress in that direction ...
